In this paper, laminar convective heat transfer in a two-dimensional microtube (MT) with 50?m diameter and 250?m length with constant heat flux is numerically investigated. The governing (continuity, momentum and energy) equations were solved using the finite volume method (FVM) with the aid of SIMP...
